member and mechanism cooperating therewith The present invention relatesto a machine for operating on shoes, and moreparticularly to the provision in a shoe machine of a control mechanism which is rendered operative by contact with the shoe to automatically control the operation of the machine in the performance of such of its various functions as may be expedient or desirable.

The present invention is herein disclosed as embodied in an inseam sewing machine for sewing together the welt, upper and insole of a welt shoe, such, for instance, as that disclosed in the patent to Eppler No. 1,108,560, dated August 25, 1914.

In embodying the present invention in this machine, a shoe contacting control mechanism is provided which is well adapted for use in that class of work in which the sewing operation extends from the breast line of the heel on one side of the shoe around the toe to the breast line of the heel on the other side of the shoe with a resulting rotation of the shoe with relation to the sewing instrumentalities through substantially 180, and also for that class of work in which the sewing operation extends entirely around a shoe sole from the starting point, causing the shoe to be turned a complete revolution with relation to the sewing instrumentalities. It will be clearly understood, however, that the several features of the invention while particularly well adapted for use in a machine of this description, are not to be limited to this type of machine, or specifically to a sewing operation, but are equally applicable to any machine for operating on shoes in which the operating point is carried progressively around the edge or margin of the shoe sole.

A main object of the present invention is to provide, in a machine in which the shoe is held in the hand of the operator, novel'and improved mechanism controlled from the shoe which is well adapted to perform automatically certain operations usually controlled. by the operator as the point of operation progresses about the shoe, and more particularly in stopping the machine at the end of the operation on the shoe.

More specifically, it is an object of the present invention to provide mechanism which is automatically adjusted by contact with the shoe when the shoe is placed in the machine, and is actuated by contact with the shoe at'the end "of the operation on the shoe to stop the machine.

With these and other objects in view as may hereinafter appear, a principal feature of the invention consists in the provision of a shoe contact rendered operativeby engagement of the shoe with the memberatthe end of the operation on the shoe to perform the. required functions in completing the operation on the shoe. H Another feature of thepresentinventionconsists in the provision of one or more.shoe engaging members and ,mechanism cooperating there- ;With rendered operative by contact withthe shoe positioned one at each sideof-the sewing point and inter-connected to cause saidlevers to be maintained atequaldistances from. the sewing point, while permitting movement thereof simultaneously toward and away from the shoe.

The several features of the invention consist also in the devices, combinations and arrangement of partshereinafter described andclaimed,

which together with the advantages to be obtained thereby, will be readily understood by one skilled in the art from the following description when taken in connection with the accompanying drawings,'in whichFig.. l is a view in front elevation of the head of an inseam sewing machine illustrating the application of the present invention thereto; Fig. 2 is a. view in front elevation partly in section and with parts broken away to show particularly a stopping mechanism for the machine; Fig. 3 is adetail plan view with parts broken away to illustrate portions of the stopping mechanism; Fig. 4 is a view in left side elevationof substantially the parts shown in Fig. 2 taken on the line 4-4 of Fig. 2 Fig. 5'is a detail view. on an enlarged scale partly in section of the control mechanism illustrated in Fig. l for throwing the stop motion of the machine into operation. 1

Figs. 6 to 9 incl'usive are a series of somewhat diagrammatic views in side elevation showing different positions taken by a shoe with relation to the shoe contact members during the operation of sewing the welt from breast line to breast line of the heel around the toe of the shoe; Figs. 10 to 14 inclusive are a series of somewhat diagrammatic view. in side elevation showing different positions taken by a right shoe with relation to the shoe' contact members during the sewing of a welt completely around the shoe starting at the inside breast line of the heel; Figs. 15 to 18 inclusive are a series of somewhat diagrammatic views in side elevation showing the several positions taken by a left shoe with relation to the shoe contact members during the operation of sewing a welt completely around the shoe; and Fig. 19 is a planview of the toe of the shoe as shown in Fig. 18, the parts in their full line position showing the stoppos'ition of the shoe contact member.

The machine illustrated in the drawings, is provided with a curved hook needle 10, a lower I2, a thread arm l4, a take-up and an auxiliary takeup, a chnanel guide l8, a welt guide 20, and a back rest 22, these parts having the same construction and mode of operation as those in the machine of the Eppler patent above referred to.

As in the patent above referred to, the sewing and work feeding instrumentalities are operated from a horizontal cam shaft indicated at 24 in the head of the machine.

The machine isdriven from an outside source of power by means-tofa-belt' 'p'ulley 26 which is Ashworth No. 1,519,652, dated December 16, 1924.- -As bestshown in Fig.2 of; the drawings, this mechanism comprises two cooperating clutch members 28"and-30 mounted respectively on the pulley Hand on a. fly wheel 32 arranged to rotate with the camshaft 24. In order to'provide means for engaging and dis-engaging the clutch members, the pulley 26 is mounted for endwise movement on the shaft, and carries a sleeve hub 34 grooved to receive two rolls'36 mounted on the forked upper end of a'clutch actuating lever 38 which is arranged to turn on a pivot 40 fixedly secured to the machine frame;

As in the machines described in the above-mentioned patents, mechanism is'provided which is rendered operative when the main clutch members 28 and 30 are disengaged in stopping the machine to gradually retard and reverse the direction of drive, and thereafter to stop the machine in a" predetermined angularvposition with the needle withdrawn from the work.

This mechanism comprises an auxiliary/slow speed driving cone clutch member 42' (see Figs. 2, 3 and 4) which is' sleeved to turn on the cam shaft 24 and is continuously driven in a reverse direction from a low speed driving pulley 44 through connections which include a shaft 46 to which the pulley is secured, a worm 45 on the shaft, and a spiral gear 41 meshing therewith formed on the outer periphery of the clutch member 42. A cooperating clutch member 48 is carried on a sleeve 50 which is keyed to rotate with and is slidable lengthwise of the cam shaft 24. A compression spring 52 seated in a recess 54 in the flywheel 32 and arranged to act on a pin 58 secured to the sleeve 50 and extending within the recess tends to hold the clutch member 48 out of engagement with the driving clutch member 42.

Upon the disengagement of the main driving clutch members 28 and 30 in stopping the machine, the clutch member 48 is moved into frictional contact with the. reversely driven clutch member 42 to gradually retard and reverse the direction of driveof the machine through connections which comprisea bell-crank cam lever 59 mounted to turn on a pivot shaft 60, and provided at one end with a. cam roll 62 which engages With the cam groove 64 in the sleeve 50, and provided at its other end with an aperture to receive a vertically movable locking bolt or pin 55 carried by a spring-pressed locking bolt carrier 66 arranged to slide in a horizontal plane in the machine. During the normal operation of the machine, the pin is held in retracted position out of engagement with the cam lever 59, so that the lever can swing idly without affecting the position of the clutch sleeve 56. In stopping the machine the locking bolt 65 is released, causing the locking bolt to engage in the aperture to lock the cam lever 59 against further movement. The continued rotation of the cam shaft 24 and the sleeve 56 then causes the sleeve to be advanced against the pressure of its spring 52 to engage the clutch and reverse the direction of drive. During this reverse rotation the engagement of the cam roll 62 on the bell-crank 59 with the cam groove 84 causes the sleeve 50 and clutch member 48 to be moved to the left as shown in Fig. 2 to disengage the slow speed or auxiliary clutch. The machine is stopped in a predetermined angular position by means of a braking and locking mechanism which comprises a bell-crank locking lever 10 (see Fig, 4) pivoted at 72 on the machine frame and having a horizontal arm arranged to engage a shoulder 13 on a disk 76 secured to the cam shaft 24. An upwardly extending arm of the bell-crank locking lever 13 has journalled therein a rock shaft 78 having at one end an offset crank pin ?9 to which is secured a friction brake band 86 which extends over a portion of the periphery of a brake disk 8! and is secured at its other end at 82 on the machine frame. The locking lever '10 is moved about its pivot to swing its horizontal arm into locking position, and also to exert the tension upon the brake upon reversal of the drive by means of an actuating lever 84 pivotally secured to the upper end of the locking lever 76 and provided with two segmental surfaces, the upper one of which runs against a sleeve on the cam shaft 24 during the forward rotation of the cam shaft. When the rotation of the cam shaft is reversed, the notch in the sleeve acts on the lever and rocks it into the position indicated in dotted lines in Fig. 4, thus causing the horizontal arm of the locking lever iii to enter the slot to engage the shoulder 73 and positively stop the machine.

leverarm 90 which 'is pivoted on the lock bolt carrier 66, and is connected intermediate its length to the lower end of the lock bolt or pin 65, so that the position of the lock bolt 65 is controlled by the position of the control rod 83. The

vertical movements of the control rod 38 are also utilized to position the rock shaft 78 to bring the brake band 80 into operating position through connections comprising a pin 94 secured to the upper end of the control rod 88 and arranged to engage in a slot 96 formed in an arm 96 secured to turn with the rock shaft 18 and crank pin 19. In order to control the movement of the main clutch actuating lever 38, the control bar 83 is arranged to extend through a collar I03 formed in the freeend of the lever 38, and is provided with stop sleeves IBZand I04 located respectively above and below the collar I00 so that endwise formed in the bracket II6.

pivot by the engagement therewith of the collar I02 to close the main clutch and start the machine. Conversely, the upward movement of. the control rod 88 acts to release the main -driving clutch 38, raises the lock bolt into the path of the bell-crank 59 for controlling the operation of the auxiliary clutch, and moves the .crank pin I9 about its pivot to bring the brake. band into operative position.

With the present construction the control rod 88 is actuated from the starting. treadle of the machine by means of a treadle rod I06 whichis provided at its upper end with a hook I88 arranged to engage witha corresponding ledge I I0 formed on the control rod 88. A compression spring II 2 seated at one end on a platform II 4 on the machine frame and at its other end bearing against the lower end of the control rod 88, tends to maintain the control rod in a raised position with the ledge III) in engagement withthe hook I08. The treadle .rod I06 and the control rod 88 are supported to maintain their positions 7 with relation to each other by means of a bracket II6 secured by a bolt II8 to a fixed portion of the'machine. The control rod 88 is supported for vertical sliding movements in a bearing I20 The treadle rod I06 is supported for vertical movements and also for movements laterally toward and away from the control rod 88 in a vertical slot I22 formed in the end of the bracket HE. A tension spring I24 connected at one end to the treadle rod I06 and at its other end to a fixed portion of the machine tends to hold the treadle rod to the right as shown in Fig. 2 in close proximity to the control rod 88.

In carrying out the several features of the present invention, the machine illustrated in the drawings is provided with two shoe contact members I26 and I28 which are located at equal distances to each side of the sewing mechanism including the needle I0, and are supported respectively on the downwardly extending arms of two bell-crank shaped shoe contact levers I30 and I32 which are secured to pivot shafts I34 and I36 on the machine frame, and are connected to move together by the engagement of two gear segments I38 formed respectively on the laterally extending arms of the bell-cranks I30 and I32. A spring I40 coiled about the pivot shaft I36 andsecured at one end to the shaft and at its other end to the machine frame tends at all times to hold the levers and contact members I26 and I28 at their limiting positions towards the needle.

Each of the shoe contact plates I26 and I28 has formed thereon lugs I4I perforated to receive a vertical post I42 which at its upper end engages in a recess formed in the downwardly extending arm of the corresponding bell-crank lever I30 or I32. Set screws I44 hold the posts I42 rigidly in position on the levers I30 and I32, and set screws I46 are provided to clamp the shoe contact members I26 and I28 rigidly in adjusted position on the posts I42. The shoe contact member I28 on the left side of the machine as seen in Fig. 1 comprises a flat plate which is set in a vertical position at right angles to and somewhat "above'the shoe sole when placed inv a substantially horizontal position in the machine. The shoe contact member I 26 similarly comprises a flat plate setat right angles to and slightly above the point of operation at the right side of the machine as seen in Fig. l. The forward edge of the plate or member I26 is further provided with a bent portion I58 along its front edge as best seen in Fig. 19 to provide a. cam surface for a purpose hereinafter to be described. I

At the startof an operation on a shoe, the shoe contact plates I26 and I28 and their supporting levers I30 and I32 are adjustably positioned in accordance with the size of the shoe placed in .the machine by engagement of the toe of the shoe with one of the plates I 26, I28, and areheldin this position during the operation by means of a mechanism which is actuated by contact of the shoe with one of these plates at the end. of the operation to throw into operation the stopping mechanism of the machine. The mechanism for maintaining the shoe contact plates I26 and' I28 in their adjusted position, and for throwing the stopmotion of the machine into operation, comprises a downwardly extending arm I52 which is secured to the rear end of the pivot shaft I36,

and at its lower end is provided witha U-shaped support I54 and a pin I56 on which are carried two pawls I58 slightly out of line with each other. Cooperating with the pawls I58 is arack I68 which is slidably mounted in a fixed bracket I62, and extends through the aperture. formed by the U-shaped support I54; At one end the rack I68 is arranged to slide in the forked end. I64 of the fixed bracket I I6, and is perforated to receive the lengthwise 'movable foot treadle, rod I66. With this construction of the parts, it will be seen that a movement of the rack I60 to theleft as shown. in Fig. 2, will cause the upper end of the treadle rod I06 to be moved to the left against the pressure of its spring, disengaging the latch I08 fromthepro jection IIO to release the stop control rod 88 and stop the machine.

The pawls I58 are disengaged from the rack I60 when a new shoe is placed in the machine, to

permit an'adjustment of the arm I52 and shoe pawl release member I68 is mounted on the lower end of a vertical rack I14 mounted'to slide in a fixed bracket I16, and arranged to engage with a pinion I'I8 which in turn engages with a horizontally movable rack I80 mounted to slide in the bracket I16. A compression spring I82 inserted between a collar I84 on the upper end of the rack I14 and an offset portion I86 of the bracket I16, tends to maintain the rack I14 and the pawl release 'member I68 in their limiting low position with the collar I84 in engagement with the bracket I16 and with'the pawls disengaged The rack I80 is forked at one end, one'member of the fork passing to each side of the 'treadle" rod I86 'andthe control rod 88, and carries a. pin J88 mounted between the arms of thefork to engage with an inclined cam surface I90 on the control til shoe.

member I68, allowing the pawls I58 to move into locking engagement with the rack I60, so that the shoe contact members I26. and I28 are held in their adjusted position., At the end of the sewof the machine insewing a welt completely around ing operation,v the toe of the shoewill again engage with one of the shoe contact members I26 or I28, causing the shoe contact levers I30 and I32 to be moved outwardly, and through the engagement of the pawls I58 with the rack I60, causing the rack I60 and treadle bar I06 to be moved to the left as illustrated in Figs. '2 and 5 to release the stop rod 88 and stop the machine.

The operation of the machine in sewing shoes is illustrated in a somewhat diagrammatic fashion in Figs, 6 to 19 inclusive of the drawings.

Figs. 6 to 9 illustrate the manner in which the shoe is manipulatedin the hands of the operator during a sewing operation to sew a welt from the breast line of the heel around the toe to the breast line of the heel on the other side of the shoe, and applies equally to a left .or a right shoe. It will be noted from a consideration of these views that the shoe contactmembers-l26and I28 are positioned above the plane of operation on the shoe while the shoe is in itsnormal operating position during the sewing operation. vIt is usual for the operator in sewing a welt shoe when starting the operation to place the shoe in the machine with the toe in an elevated position for the formation of the firststitch. With the shoe in this, position as illustratedin Fig. 6, the toe is elevated into line with the shoe contact member I26 and engages therewith, so that the contact members. I26 and I28 are positioned in accordance with the length of shoe being operated upon. The operator nowldepresses thefoot treadle to start the machine, causing the shoe contact members I26 and I28 to be locked in their adjusted position as above described. As the operation on the shoe progresses along the shoe sole, the shoe is returned by the operatorto a substantially level position. Figs. 7 and 8 illustrate two positions of the shoe immediately before and after the operation has progressed around the toe of the As the point of operation approaches the breast line of the heel on the opposite side of the shoe from the starting 'position,.the .toe of the shoe is again elevated by .the operator into line with the shoe contact member I28, so that continued feeding of the shoe past the shoe operating devices causes the toe of the shoe to engage with the contact member I20 and move it to the left as shown in Fig. 9, causing the stop motion to be thrown into operation to stop the machine as above described.

Figs. 10 to 14 inclusive illustrate the operation of the machine in sewing a weltcompletely around the shoe sole of a right shoe. As shown in'Fig. 10 of the drawings, the shoe is placed in the machine with thetoe to the left to start the operation at the inside breast line of the heel. The toe is elevated by the operator in placing the shoe in the machine, so' that the toe engages with the shoe contact member I2B.which is locked in position .upon depressing the foot treadle as-above described. As the sewing operation starts, the

toe is immediately depressed to a substantially level position below the plane of the contact memger I28' as shown in Fig. 11, so that as the shoe is fed to the left, the toe passes beneath the contact member I28. 'Figs. 12 and 13 illustrate different positions of the shoe as the sewing operation progresses around theshoe sole. As the sewing operation nears. completion, the toe is again elevated. by the operator into engagement with the contact member. I28 which is moved to the left to throw the stop motion of the machine into operation as above described.

Figs. 15 to 19 inclusive illustrate the operation the shoe sole of a left shoe. As shown in Fig. 15 of the drawings, the shoe is placed in the machine with the toe toitherightto start the operation at the inside breast line of the heel; The toe is elevated by the operator in placing the shoe in the machine, so that the toe engages with the shoe contact member I26 which is locked in position upon depressing the foot treadle as above described. Uponstarting the operation, the shoe is immediately returned to its substantially level position below the plane of the contact members I26 and I 28. Figs. 16 and 17 illustrate different positions of the shoe during the progress of the sewing operation about the shoe sole. As the operation again approaches the breast line of the heel, the toe of the shoe is again elevated by the operator, and is moved inwardly, so that the toe engages with the cam surface-l50 of the contact member I26, causing this member to be moved outwardly as shown in Figs. l8 and 19 to throw the stop motion of the machine into operation.
